Glaucoma attacks and damages the optic nerve of the dog’s eye. The most common causes are high eye pressure, eye injury, which leads to trauma-based glaucoma, hereditary predisposition, and age-caused changes.

While cataracts do not usually cause pain, glaucoma does. If your pup has glaucoma, he’ll show symptoms like continuously pawing at his eye, lethargy, squinting, reddened eyes, and reduced appetite.

Glaucoma-induced sight loss has a 50% chance of reversing back. These are the two most common illnesses you will encounter when researching what can make a dog go blind overnight.

Many eye diseases can be reversed if diagnosed and treated on time, whereas many cannot be undone. Such as sudden acquired retinal degeneration or progressive retinal atrophy, for these have no treatments invented yet.

But doctors can treat conditions such as cataracts with surgeries by replacing the eye lens with an artificial lens.

If you noticed symptoms and started treating your doggie after taking him to a doctor, the diseases which cause dogs to go blind can be eradicated or slowed down.

Either way, the main thing you should do is check your dog’s eyes properly from time to time. Because some illnesses develop rapidly and you might get caught off guard after learning that your dog has lost his sight one day.
